Black filled star.
Each row and column has to contain each kind of pentagram.
Also: I think it is the diagonals? Similar to determinant rule application.

can you expand on the xor reference? I do not see the connection to boolean logic? You mean its an all unequal relation for rows and columns?
For instance, compare the first and second columns. When you examine corresponding segments of the two stars, the third column will be shaded only if the segments in the first two stars differ in shading. In other words, it behaves like an XOR operation.
